Samples Number 99 to 101 and 107: CHL:Bottle - ~20 ml of sample missing. Analysis methods: ----------------- Salinity samples were collected in glass bottles and analyzed on a Guildline model 8400B Autosal or a Guildline Portasal 8410A. Salinometers are standardized with IAPSO standard seawater. See file 2008-001_SAL.pdf for information on precision and duplicates. Oxygen samples were analyzed on an automated Winkler titration system following the procedures of Carpenter (1965). Samples were analyzed at sea using an automated titration system consisting of a Brinkman Dosimat (model 665) and a PC 900 Colorimeter. For details on precision see file 2008-001_OXY.pdf. Nutrient samples were collected in plastic tubes and analyzed fresh at sea using a Technicon AAII autoanalyzer following methods described in Barwell-Clarke and Whitney (1996). For details on nutrient duplicates and precision see file 2008-001_NUT.pdf. Chlorophyll samples were analyzed at sea using a Chemistry Turner Designs fluorometer which was calibrated in May 2007 using pure chlorophyll a. Chlorophyll precision was determined by analyzing replicate samples drawn from one Niskin. For details see file 2008-001_CHL.pdf. The minimum detectable level for DMS is 0.10 nM, so “0” values should be interpreted as <0.10. For details on the collection and analysis of the DMS data see file 2008-001_DMS_report.pdf. For details on duplicates see file 2008-001_DMS.pdf. Dissolved inorganic carbon (DIC) was determined using coulometric analysis. Total alkalinity (Alk) was determined by potentiometric titration. pH on the total hydrogen ion concentration scale was determined photometrically and is reported at 25C and surface pressure. For duplicates and precision of DIC, ALK and pH samples see files 2008-001_DIC.pdf, 2008-001_ALK.pdf, and 2008-001_pH.pdf respectively. HPLC samples were filtered onto 25mm GF/F filters and stored at -80C prior to analysis. Samples were extracted in 95% methanol at -20C for 24 hours and analyzed on a WATERS 2695 HPLC separations system as detailed in Nemcek and Pena, 2014. Analysis was performed ~2 weeks after collection. The average of two samples is reported. Variability is assessed as the %CV (std dev/mean*100) for duplicate pairs. All pigments below the limit of detection (LOD) are assigned a zero value. TChl-a is the sum of Chl-a, DVchl-a and Chlide-a. References: 1. Carpenter, J.H. 1965.

Data Processing Notes: ---------------------- WARNING: All samples from Bottles Number 13 to 18 should be treated with care. While the CTD data correspond to the level at which the bottle were fired, in many cases the bottles closed earlier. Notes in the headers of individual files indicate the probable level at which bottles closed, where evidence exists to make that estimate. For details on the processing see processing report: 2008-001-proc.pdf $REMARKS Quality flags have the following significance: ---------------------------------------------------------------------------------- 0 = Acceptable measurement with no header comment. 1 = Sample for this measurement was collected but not analyzed. Sample lost. 2 = Acceptable measurement with header comment. 3 = Questionable measurement (probably good). 4 = Poor measurement (probably bad). 5 = Measurement not reported (bad). 6 = Mean of replicate measurements. 7 = Manual chromatographic peak measurement. 8 = Irregular digital chromatographic peak integration. 9 = Sample was planned for this measurement from this bottle but was not collected. ----------------------------------------------------------------------------------- $END !-1-- 2- --3--- ---4---- ---5---- ---6---- --7-- --8--- --9-- ---10-- ---11--- 12 ---13-- 14 --15- 16 --17-- 18 --19- 20 --21-- 22 !Samp Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores Salinity Fl Oxygen: Fl Nitra Fl Phosph Fl Silic Fl Chloro Fl !le_ tt re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: :Bottle ag Dissolv ag te_pl ag ate: ag ate: ag phyll: ag !Numb ~u vity: lved: solve CTD: ~o ed: ~o ~Nitr ~o Bottle ~o Bottl ~o Extrac ~o !er mb CTD CTD: d:CTD Seapoin tt Bottle: tt ite:B tt tt e tt ted: tt ! er Volume :Mass t le Volume le ottle le le le Bottle le !---- -- ------ -------- -------- -------- ----- ------ ----- ------- -------- -- ------- -- ----- -- ------ -- ----- -- ------ -- *END OF HEADER 107 24 7.0 6.8306 32.4812 25.4833 55.1 6.96 303.1 0.883 32.4859 3 6.793 0 12.0 0 1.20 0 14.3 0 1.01 2 106 23 6.6 6.8303 32.4812 25.4834 55.2 6.97 303.4 0.868 -99.0000 0 -99.000 0 -99.0 0 -99.00 0 -99.0 0 -99.00 0 105 22 10.3 6.8320 32.4806 25.4827 55.4 6.96 303.0 0.860 -99.0000 0 -99.000 0 -99.0 0 -99.00 0 -99.0 0 -99.00 0 104 21 10.1 6.8275 32.4807 25.4833 55.2 6.96 302.8 0.902 -99.0000 0 -99.000 0 -99.0 0 -99.00 0 -99.0 0 -99.00 0 103 20 10.1 6.8298 32.4807 25.4830 55.1 6.96 303.2 0.885 -99.0000 0 -99.000 0 -99.0 0 -99.00 0 -99.0 0 -99.00 0 102 19 10.1 6.8323 32.4806 25.4826 55.2 6.96 303.2 0.827 32.4852 3 6.804 0 11.9 0 1.20 0 14.1 0 0.80 0 101 18 24.8 6.8311 32.4800 25.4823 55.7 6.93 301.7 0.771 32.4873 3 6.789 0 11.9 0 1.19 0 14.5 0 0.69 2 100 17 50.1 6.8325 32.4863 25.4871 56.9 6.90 300.3 0.726 32.4911 3 6.761 0 12.1 0 1.19 0 14.6 0 0.64 26 99 16 75.2 7.0750 32.6766 25.6047 58.9 6.32 275.0 0.433 32.6347 3 6.325 0 13.9 0 1.30 0 17.0 0 0.32 2 98 15 100.0 7.1826 33.4276 26.1811 60.2 4.29 186.6 0.137 33.4099 3 4.285 0 23.9 0 1.82 0 29.8 0 0.03 0 97 14 125.7 7.3878 33.6860 26.3559 59.5 2.96 128.8 0.128 33.6866 3 2.897 0 29.3 0 2.20 0 39.3 0 -99.00 0 96 13 149.6 6.8442 33.7593 26.4884 60.5 3.78 164.4 0.118 33.7515 3 3.941 0 26.3 0 1.93 0 36.8 0 -99.00 0 95 12 175.6 6.9715 33.8979 26.5804 60.0 2.35 102.3 0.124 33.8998 3 2.315 6 32.4 0 2.37 0 47.0 0 -99.00 0 94 11 200.6 6.6273 33.9053 26.6325 60.4 2.57 111.7 0.121 33.9120 3 2.441 0 32.6 0 2.37 0 48.8 0 -99.00 0 93 10 248.7 6.1907 33.9145 26.6966 60.7 2.45 106.8 0.123 33.9171 3 2.451 0 33.5 0 2.42 0 53.6 0 -99.00 0 92 9 300.6 6.0290 34.0094 26.7921 60.7 1.35 58.8 0.123 34.0130 3 1.364 0 38.1 0 2.77 0 64.7 0 -99.00 0 91 8 400.5 5.4453 34.0730 26.9140 61.0 0.88 38.1 0.122 34.0755 3 0.854 0 40.7 0 2.97 0 77.6 0 -99.00 0 90 7 600.0 4.4885 34.2056 27.1284 61.2 0.35 15.2 0.121 34.2084 3 0.323 0 43.7 0 3.20 0 102.3 0 -99.00 0 89 6 798.3 3.8498 34.3134 27.2811 61.3 0.24 10.5 0.121 34.3155 3 0.239 0 44.6 6 3.27 6 121.8 6 -99.00 0 88 5 999.5 3.2875 34.3829 27.3915 61.4 0.27 11.8 0.119 34.3896 3 0.241 0 45.1 0 3.28 0 138.0 0 -99.00 0 87 4 999.9 3.2847 34.3827 27.3916 61.4 0.27 11.8 0.120 34.3851 3 0.238 0 45.2 0 3.28 0 137.9 0 -99.00 0 86 3 1248.8 2.7775 34.4548 27.4956 61.5 0.41 17.8 0.119 34.4586 3 0.382 0 45.2 0 3.26 0 154.0 0 -99.00 0 85 2 1500.9 2.4122 34.5103 27.5715 61.5 0.70 30.5 0.117 34.5136 3 0.729 0 44.5 0 3.19 0 164.4 0 -99.00 0 84 1 2000.9 1.9307 34.5918 27.6758 61.3 1.41 61.3 0.114 34.5956 3 1.481 0 42.5 0 3.07 0 177.7 0 -99.00 0
